Purpose: These data are intended for policy makers, resource managers, science researchers, technical users, students, and the general public. These data can be used with geographic information systems or other software to identify and assess possible areas of vulnerability. These data are not intended to be used for navigation. Supplemental_Information: This work is one portion of ongoing modeling efforts for California and the western United States. The Coastal Storm Modeling system uses several tiers of numerical models to make detailed predictions (meter-scale) of flooding and erosion over large geographic scales.

Significant wave height and velocity were similarly processed from tier 2 sub-regional models. For each output variable, maximum values for all contributing events in a storm scenario are composited to show the total maximum value for the scenario at each grid point from all simulations (for example, maximum output for all 100-year storm events are composited to a single 100-year scenario data layer). See O'Neill and others (2018, 2024) for information on CoSMoS framework, set up for simulations, and processing. Maximum output for water elevations were depth-differenced to the DEM to separate low-lying vulnerable areas from contiguous coastal flooding. Other output data (water elevation, flood depth, maximum current velocities, maximum wave heights) were clipped to final flood hazard extent. Flood potential projections (maximum and minimum flood uncertainty) were derived by adding/subtracting estimated model error, DEM uncertainty, and projected VLM for a given SLR to the respective water elevation surface. See O'Neill and others (2018) for a full discussion.
